Colorectal Carcinoma-An Anomalous Trigger of Adult Hemophagocytic Lymphohistiocytosis.

Hemophagocytic lymphohistiocytosis (HLH) is a rare but often fatal condition characterized by a hyperinflammatory immune response leading to multiorgan failure. It is predominantly observed in the pediatric population and can be classified as familial or acquired HLH. The latter is more common in adults, often associated with malignancy, infection, or autoimmune diseases. Among acquired HLH cases, hematologic neoplasms account for the majority, with only a few isolated reports documenting solid neoplasms as the cause. Herein, we present a case of adult HLH associated with colorectal adenocarcinoma, which, to the best of our knowledge, is only the second reported case of HLH associated with this type of cancer.

Multicentric Case Series and Literature Review of Coccidioidal Otomastoiditis.

Coccidioidomycosis involving the ear, mastoid bone, or both is uncommon. We describe 5 new cases from the United States and review 4 cases reported in the literature of otomycosis and mastoiditis caused by Coccidioides. Of the 9 cases, 8 were linked to residence in or travel to California. Two patients had poorly controlled diabetes mellitus, 7 had otomastoiditis, 1 had otitis externa without mastoid involvement, and 1 had mastoiditis without otic involvement. Four patients had concurrent or prior pulmonary coccidioidomycosis. Ipsilateral facial nerve palsies developed in 2 patients. All patients received antifungal treatment for varying durations, and 8 of the 9 patients underwent surgical debridement. Clinicians should consider coccidioidomycosis as a differential diagnosis for otomastoiditis in patients with geographic risks.

A Case of Disseminated Histoplasmosis From California, in the Setting of Secondary Hemophagocytic Lymphohistiocytosis: A Diagnostic Challenge.

Histoplasma capsulatum is a geographically specific dimorphic fungus that can cause a spectrum of diseases. While most cases are asymptomatic pulmonary infections, in severe cases, particularly in immunocompromised patients, disseminated disease can occur. Histoplasmosis in California is limited to only a few case reports. In this article, we describe a rare case of disseminated histoplasmosis in a non-endemic region presenting with diagnostically challenging symptomatology, including altered mental status, status epilepticus, septic shock, and bilateral adrenal masses.

A Rare Hemorrhagic, Orange-Colored Ascites, Challenging Traditional Ascitic Fluid Analysis.

Analysis of ascitic fluid can offer useful information in developing and supporting a differential diagnosis. As one of the most prevalent complications in patients with cirrhosis, ascitic fluid aids in differentiating a benign condition from malignancy. Both the gross appearance of the ascitic fluid, along with fluid analysis, play a major role in diagnosis. Here, we discuss a patient with liver cirrhosis, esophageal varices, hepatitis C, and alcohol abuse, who had a paracentesis performed, which revealed a turbid, viscous, orange-colored ascitic fluid that has not been documented in literature. Ascitic fluid is routinely analyzed based on gross appearance, cell count, and serum ascites albumin gradient (SAAG) score. An appearance of turbidity or cloudiness has commonly suggested an inflammatory process. In our case, fluid analysis revealed a red blood cell count of 24 250/mcL, further suggesting inflammation. However, it also revealed an insignificant number of inflammatory cells, with a total nucleated cell count of 14/mcL. This rich-orange color has posed a challenge in classification and diagnosis of the underlying cause of ascites, with one classification system suggesting inflammation, while another suggesting portal hypertension. Furthermore, we have traditionally relied on the SAAG score to aid in determining portal hypertension as an underlying cause of ascites. With a 96.7% accuracy rate, the SAAG score incorrectly diagnosed portal hypertension in this patient. In this article, we aim to explore how this rare, orange-colored ascitic fluid has challenged the traditional classification system of ascites.

Immune Thrombocytopenia following COVID-19 Vaccine.

Several vaccines have been developed and are being administered against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Common side effects include fever, chills, headache, myalgia, and soreness at the injection site. However, some rare adverse effects have also been reported. We present a case of induced thrombocytopenia presenting with petechiae and mucosal bleeding which developed as an adverse response after first-dose administration of the Moderna COVID-19 vaccine.

Erythrodermic Psoriasis and Staph-Infective Endocarditis-A Conundrum in Succession.

Erythrodermic psoriasis is a rare subtype of psoriasis vulgaris that presents with diffuse erythema and desquamation over greater than 75% of the body's surface area. We present a case of a 57-year-old male who was admitted with a diffuse, erythematous scaly rash covering his entire body, with associated subjective fevers. Skin biopsy revealed erythrodermic psoriasis, and blood cultures were positive for methicillin-sensitive Staphylococcus aureus. Echocardiogram revealed a mitral valve vegetation. Clinical improvement was achieved with intravenous antibiotic administration and topical corticosteroids without the use of immunomodulators.

Two Cases of Pelvic Diffuse Large B-Cell Lymphoma.

Primary diffuse large B-cell lymphoma presenting as an extranodal site in the pelvis is rare and can mimic a gynecological malignancy. Although management for diffuse large B-cell lymphoma is standardized and curative, prognosis depends on timely diagnosis and therapy. Diagnosis can be challenging as patients lack classical symptoms of fever, night sweats, weight loss, and lymphadenopathy associated with lymphoma. A multidisciplinary approach is recommended to diagnose and treat judiciously. In this article, we present cases of 2 females who presented with pelvic masses with initial suspicion of a gynecological malignancy but were ultimately diagnosed as diffuse large B-cell lymphoma of the pelvis and managed accordingly.

Serum magnesium levels in hospitalized patients with SARS-CoV-2.

Early studies have reported various electrolyte abnormalities at admission in patients with severe COVID-19. 104 out of 193 patients admitted to our institution presented with hypermagnesemia at presentation. It is believed this may be important in the evaluation of severe SARS-CoV-2 infections. This study evaluated the outcomes of hypermagnesemia in patients with COVID-19. A retrospective chart review of patients admitted to the hospital with confirmed SARS-CoV-2 infection was conducted. A review of the medical literature regarding hypermagnesemia, magnesium levels in critical care illness and electrolyte abnormalities in patients with COVID-19 was performed. Differences in demographic and clinical characteristics of patients with hypermagnesemia and normomagnesemia were evaluated using descriptive statistics. Other known variables of disease severity were analyzed. 104 patients (54%) were identified with hypermagnesemia (≥2.5 mg/dL). 48 of those patients were admitted to the intensive care unit (46%, p<0.001). 34 patients required ventilator support (32%, p<0.0001). With age-adjusted logistic regression analysis hypermagnesemia was associated with mortality (p=0.007). This study demonstrates that hypermagnesemia is a significant marker of disease severity and adverse outcome in SARS-CoV-2 infections. We recommend serum magnesium be added to the panel of tests routinely ordered in evaluation of severe SARS-CoV-2 infections.

The First Case Report of Endocarditis Caused by Serratia fonticola.

The cases of human infections caused by Serratia fonticola are relatively rare. The few cases that have been reported primarily describe skin and soft tissue, urinary, and biliary tract infections. We describe a case of a 59-year-old man with infected bilateral lower extremity wounds who developed endocarditis due to S fonticola confirmed with transesophageal echocardiogram. The patient was treated with 6 weeks of antibiotic therapy and had an uneventful recovery. After a thorough review of the literature using PubMed and Google Scholar, we concluded that this is the first reported case of endocarditis caused by S fonticola.

Wound Botulism in Black Tar Heroin Injecting Users: A Case Series.

The incidence of wound botulism in injection drug users has increased since the introduction of black tar heroin. Many species of the Clostridium genus, most commonly Clostridium botulinum, Clostridium baratii, and Clostridium butyricum, have been associated with wound botulism. Patients often present with progressive bulbar weakness, including dysphagia, cranial nerve palsies, and loss of speech, in addition to symmetrical descending weakness of the upper extremities that may progress to the chest and lower extremities. In this article, we present 3 cases of wound botulism, in which the patients presented with bulbar weakness and were treated with botulism antitoxin heptavalent. The time to antitoxin administration and its effect on the patients' clinical courses is compared.

An Unusual Case of Hemophagocytic Lymphohistiocytosis Presentation in Acute Human Immunodeficiency Virus.

Hemophagocytic lymphohistiocytosis (HLH) in acute human immunodeficiency virus (HIV) patients has been scarcely reported in the English literature. To the best of our knowledge, only 12 cases have been described. We present a case of a 27-year-old male with no past medical history who was admitted with a new-onset headache, fever, night sweats, and chills. Further laboratory tests revealed transaminitis, leukopenia, thrombocytopenia, positive HIV antigen/antibody test, and markedly elevated ferritin levels, which promoted our suspicion of HLH. This case demonstrates HLH as an unusual presentation of HIV during its seroconversion stage. This report adds a rare disease process to the available literature, and we emphasize that markedly elevated ferritin levels in acute HIV patients should raise suspicion toward a diagnosis of HLH.

Idiopathic Left Ovarian Vein Thrombosis.

Ovarian vein thrombosis (OVT) was first described in 1956 and is well known for its association with gynecological malignancy, pregnancy, postpartum, pelvic diseases, surgeries, and other thrombophilic etiologies. Most commonly OVT presents on the right ovarian vein. We report a rare case of a 47-year-old Caucasian female G7P7 with no significant past medical history who presented to the emergency room for acute nonspecific back pain and left lower quadrant pain of 1 day. Imaging with a computed tomography with contrast demonstrated a new left OVT. After a thorough literature review, this is presumed to be the third reported case of idiopathic left OVT.

Infective Endocarditis 2 Decades After Pulmonary Autograft Ross Procedure.

Pulmonary autograft, or Ross procedure, is performed by supplanting a diseased aortic valve with the patient's own pulmonary valve. Reconstruction of the right ventricular outflow tract is then completed using a pulmonary homograft. To our knowledge, infective endocarditis occurring decades after the Ross procedure has not been reported. Diligent echocardiographic examination can be crucial to ensure prompt treatment and avoid the 25% mortality rate associated with infective endocarditis. Clinical suspicion should remain high in those with a pulmonary autograft history. In this article, we report the case of a 39-year-old patient with infective endocarditis presenting 22 years after Ross procedure.

Disseminated Coccidioidomycosis to the Gallbladder.

Coccidioidomycosis is an infection caused by inhalation of arthroconidia produced by dimorphic fungi in the genus Coccidioides. Forty percent of patients will develop an influenza-like illness with symptoms suggestive of a mild and self-limited respiratory infection; however, 5% of these individuals will develop extrapulmonary disseminated disease. An immunocompromised patient presented with right upper quadrant pain, ultrasound with pericholecystic fluid, in which a percutaneous cholecystostomy contained biliary fluid that grew the fungus Coccidioides immitis. Patient was initiated on intravenous amphotericin therapy and was followed closely with postoperative bile drainage with eventual laparoscopic cholecystectomy. We present a very rare case of disseminated coccidioidomycosis to the gallbladder.

Erythema Sweetobullosum: A Reactive Cutaneous Manifestation of Coccidioidomycosis.

Reactive cutaneous coccidioidal skin manifestations are commonly noticed during the early stage of coccidioidomycosis. These skin lesions are devoid of any active coccidioidal organism, and the immune trigger mechanisms are not elucidated. We describe 6 cases of unusual reactive cutaneous coccidioidal manifestation, characterized by painful vesiculobullous lesions known as erythema sweetobullosum. The biopsy of the lesions revealed neutrophilic dermatosis with inflammatory cells resulting in a cleft and elevation of the most superficial layer of the skin forming a bulla. The reactive cutaneous lesion is self-limited and requires no specific therapy.

Splenic Marginal Zone Lymphoma in the Setting of Noncirrhotic Portal Hypertension.

We present a case of a 65-year-old Hispanic man with a history of disseminated cutaneous coccidioidomycosis who presented to the emergency room for progressively worsening abdominal pain associated with shortness of breath. The patient was found to have pleural effusion and moderate ascites on physical examination. Abdominal ultrasound and computed tomography scan were consistent with moderate ascites and portal hypertension but negative for both liver cirrhosis and for venous or arterial thrombosis. Cytology of ascitic fluid was suggestive of portal hypertension and was negative for infection. Subsequent, thoracentesis was suggestive of exudative effusion and also negative for infection. Liver biopsy confirmed the absence of cirrhosis. Complete blood count indicated pancytopenia, whereas bone marrow biopsy and flow cytometry were suggestive of marginal zone lymphoma (MZL). Clinically, the patient's shortness of breath was resolved by thoracentesis and paracentesis; however, his abdominal pain persisted. A diagnosis of idiopathic noncirrhotic portal hypertension in the setting of splenic MZL was made. The patient was transferred to a higher level of care for splenectomy; however, he missed multiple appointments. Since discharge, the patient has been seen in the outpatient setting and states that he is controlling his disease with diet and exercise; however, he continues to complain of intermittent shortness of breath with exertion.
